Answer 1

Define this code in onCreate.

// 5000 is the starting number (in milliseconds)
// 1000 is the number to count down each time (in milliseconds)
MyCount counter = new MyCount(5000, 1000);
counter.start();

Constructor for CountDownTimer is as follow.

// countdowntimer is an abstract class, so extend it and fill in methods
public class MyCount extends CountDownTimer{

public MyCount(long millisInFuture, long countDownInterval) {
    super(millisInFuture, countDownInterval);
}

@Override
public void onFinish() {
tv.setText(”done!”);   //TextView object should be defined in onCreate
}

    @Override
public void onTick(long millisUntilFinished) {
tv.setText(”Left: ” + millisUntilFinished/1000);// This will be called every Second.

}
}
